OpenGL Composer stops when i connect the second monitor

Support KDE Plasma
1

Hi. I need help with the following. When I connect my second monitor, the composer stops. In other words, all OpenGL desktop and graphic effects (textures, etc.) are suspended. The second monitor is a Samsung LED TV, with a resolution of 1920x1080 and a refresh rate of 60 Hz. I connect it to the Notebook via HDMI. When this happens, I can reactivate the composer using the shortcut Shift + Alt + F12, but doing so the mouse starts to malfunction, printing the image of the pointer (like a “mouse pointer trail”) all over the screen, it’s impossible to use. This faulty mouse behavior stops only if I disconnect the second monitor. When I disconnect the monitor I also need to reactivate the composer. This does not happen by selecting Xrender as the rendering engine. But I lose all the visual effects and environmental management advantages that OpenGL allows. I can not find a solution in Google or in this forum, therefore I leave my query here. I detail the Log of my laptop:

Try with that resolution, your graphics card doesn’t support FHD

Could you detail your answer?
Thank you!

Hi!
Looks like you grafics card only support HD resolution ( 137676860Hz), look your inxi output.
I’m not sure but maybe that is the problem

I understand what you’re saying. I looked up the technical specifications of the graphics card and according to laptopmedia:

“The GPU can support up to 3 displays with a maximum resolution of 4K but internally can handle only 2560 x 1440 (QHD) via eDP. The external displays can be connected via HDMI or Display Port. Other major features include the support of DirectX 12 and Open GL 4.2.”

So I assume this is a KDE Plasma or Manjaro kernel driver or configuration issue. With other distros (Ubuntu Mate, Mint Mate, even an old Manjaro xfce) I didn’t have this problem. Only with the latest Ubuntu 20.04 (Gnome) the ‘mouse pointer trail’ happened when connecting the second monitor via HDMI, but at that time I solved it by creating a file:

/etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
EndSection

But this time that alternative did not solve my problem.

Hi!
it could be problem of your tv, the xrandr output looks right, most tv have a button in the remote to configure mods of display, check the config of your tv, there are some post in the forum about it

I changed the TV connection to the ‘HDMI2’ input (previously the cable was connected to ‘DVI HDMI’). That improved the composer’s reaction to connecting the second monitor, but partially. It still continues to cause problems. OpenGL is still active but the windows disappear from the laptop screen and are positioned on the TV monitor, Plank disappears, and sometimes the mouse crashes again.

For my part I entered some extra settings. Edited /etc/X11/xorg.conf.d/10-monitor.conf:

Section "Monitor"
    Identifier  "eDP1"
    Option      "Primary" "true"
EndSection

Section "Monitor"
    Identifier  "HDMI2"
    Option      "LeftOf" "eDP1"
    Option      "Primary" "false"
EndSection

I added a new section in /etc/X11/xorg.conf.d/20-intel.conf:

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
EndSection

Section "Device"
    Identifier "Intel Graphics"
    Driver "intel"
    Option "TearFree" "true"
EndSection

And finally I edited /etc/default/grub, adding i915.enable_psr=0 to “GRUB_CMDLINE_LINUX_DEFAULT=”:

GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=00a2dcc4-b790-4742-90d7-a8d7c04a4f45 udev.log_priority=3 i915.enable_psr=0"

These modifications I found in different proposed solutions for problems similar to mine.

Thanks and regards.
